>>1428396420million triangles on 33 Million pixels.
means this demo needs 16K. you can't draw triangles on a pixel. but if you go from 8K to 16K. you have per pixel from 8K 4 Pixels in 16K.
means if you have a triangle in a pixel, you can see the correct rotation of the triangle.
so instead you have a whole triangle in a pixel, you have a triangle like pic related. it's shaping the details.
